My company (well, government entity) had started moving towards work from home several years ago. We’ve been working from home 3-4 days a week anyway for a couple of years as a cost-savings measure. It allows for a smaller office footprint because you only need to allow for say, 20 people in the office any one day instead of the full 100. You don’t have your own personal cubicle; you pick whatever spot is available when you arrive. So when we were told to stay home...well, it was another day at the office for us!
I’m an introvert so I’m perfectly happy with it! But I do believe it’s harder to team-build working this way. As for the socialization....I think it’s going to have to be similar to homeschooling. You’ll have to make your own opportunities for socialization outside work by joining community groups. I feel the socialization issue is more the result of the lockdowns as opposed to working from home.
It is also much easier to track and control the population overall—and put them under de facto intermittent house-arrest martial law. Or to know and notice when some get escorted to quarantine camps. Etc. Etc.
